Belimo AVK24A-SZ-TPC - analogue linear actuator for globe valves

Belimo AVK24A-SZ-TPC

Analogue linear actuator for 2- and 3-way globe valves, designed for stationary heating, ventilation and air-conditioning systems. In the event of a power failure, it uses energy stored in capacitors to move the valve to the selected safe position.

Key features and specifications

• Thrust: 2000 N; stroke: 32 mm.
• Rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Y operating range: 0.5...10 V; feedback signal U: 0.5...10 V.
• Motor running time: 150 s / 32 mm; safety function running time: 35 s / 32 mm.
• Power-off position (POP): adjustable using a dial from 0...100%, in 10% increments; power-fail duration (PF): 2s.
• Power consumption during operation: 5 W; at rest: 2 W; rated power: 9.5 VA.
• Power / control connection: terminals with 1 m cable, 4x 0.75 mm², 4 mm² terminal.
